FEDCO HPB-60 Hydraulic Pressure Booster Turbocharger Energy Recovery Device
Manufactured by Fluid Equipment Development Company (FEDCO), Monroe, Michigan, USA — supplied by ForeverPure Corporation, an authorized FEDCO distributor based in Santa Clara, California.
The FEDCO HPB is a hydraulic energy-recovery turbocharger that captures pressure energy from the SWRO brine reject stream and uses it to boost feed pressure into the membrane train, reducing the size and energy consumption of the high-pressure feed pump by up to 50%. The HPB family leads the turbocharger ERD category in tested transfer efficiency, exceeding 80% across the operating envelope.

Theory of Operation
Brine exits the membrane vessels at near-feed pressure. Inside the HPB, this brine drives a single-stage radial turbine wheel that is direct-coupled (one rotor, no gearbox) to a single-stage centrifugal pump impeller on the feed side. The brine's pressure energy is converted to shaft work and immediately re-imparted to the feed stream as a pressure boost. An integral variable-area brine control valve sets brine flow without an external valve. FEDCO's patented RotorFlo™ design provides internal hydraulic lubrication of non-metallic bearings, so the HPB has no external lube circuit.
Key Engineering Advantages
- Up to 50% reduction in SWRO specific energy consumption
- >80% transfer efficiency (industry-leading among turbocharger ERDs)
- Recovers >80% of brine hydraulic energy
- Patented RotorFlo™ single-piece rotor — no external lubrication
- Integral variable-area brine control valve eliminates separate brine throttle
- Self-regulating — stable under feed-quality and temperature variation
- Zero brine mixing with feed (unlike isobaric pressure exchangers)
- Lowest CAPEX among ERD classes for small-to-medium SWRO
Applications & Industries
Typical Applications
- Seawater Reverse Osmosis (SWRO) energy recovery

Frequently Asked Questions
What is the FEDCO HPB-60?
The FEDCO HPB is a hydraulic energy-recovery turbocharger that captures pressure energy from the SWRO brine reject stream and uses it to boost feed pressure into the membrane train, reducing the size and energy consumption of the high-pressure feed pump by up to 50%. The HPB family leads the turbocharger ERD category in tested transfer efficiency, exceeding 80% across the operating envelope.
What is the FEDCO HPB-60 used for?
Typical applications include seawater reverse osmosis (swro) energy recovery; high-recovery brackish-water ro; interstage pressure boosting in biturbo high-recovery ro trains. Industries served: municipal desalination, hotels, islands, and resorts, marine / offshore.
What materials of construction does the FEDCO HPB-60 use?
Wetted parts are casing & rotor: duplex ss 2205 or super duplex ss 2507. casing bolts: 316 ss. o-rings: buna-n., providing corrosion resistance suited to seawater and chloride-rich brackish-water service.
How does a FEDCO turbocharger ERD compare to an isobaric pressure exchanger (PX, iSave, APM)?
FEDCO turbocharger ERDs (HPB, HP-HEMI) recover brine pressure energy through a hydraulic turbine that directly boosts the feed stream — a single rotating assembly with no piston cycling and no brine-feed mixing. Isobaric pressure exchangers (Energy Recovery Inc. PX, Danfoss iSave, Danfoss APM) instead transfer pressure through ceramic rotors or pistons between brine and feed streams. Turbochargers are mechanically simpler, have zero brine-to-feed mixing, are well-suited to small-to-medium SWRO and packaged plants, and FEDCO's HPB demonstrates 83%+ transfer efficiency in the field.
Where can I get the FEDCO HPB-60 datasheet, performance curve, and pricing?
Datasheet, drawings, and project-specific pricing for the FEDCO HPB-60 are available on request from ForeverPure Corporation. Submit a quote request through the website with your duty-point information and the applications team will respond with model selection, options, lead time, and pricing.
